high pressure roller iron ore grinding
High pressure grinding rolls (HPGR) minevik
High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain sizeThe HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them This forces the rocks against each other and compresses the feed’s density to 80% of its solid [](HPGR) high pressure grinding rolls/rollers for cement
